HOOP-PLANER.

SPECIFICATION forming partof Letters Patent No. 279,496, dated June 12, 1883.

Application filed January 17, 1883. (No model.) I

' To all whom it may concern:

cal adjustment of the table is effected.

suitable bearings therefor.

Be it known that I, OLAF R. OLSEN, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new anduseful Improvements in Hoop-Planers, of which the following is a specification.

My said invention consists of certain improvements in the construction and arrangement of that class of machines known as 1100pplaners, as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figurel is atop or plan view of a planer embodying my invention; Fig. 2, a front elevation of the same; Fig. 3, an elevation of one end; Fig. 4, an elevation of the other end 5 Fig. 5, a vertical sectional View, as seen when looking toward the left from the dotted line 2 z in Figs. 1 and 2; Fig. 6, a view similar to a portion of Fig. 5, on an enlarged scale Fig. 7, a sectional view on the dotted line 3/ g in Fig. 1, and Fig. 8 a section of the guide I) 011 the dotted line 00 w in Fig. 6.

In said drawings, the portions marked A represent the frame of the planer; B, the bed G, the cutter-head; D D D D, the feed-rolls; D a pressure-roll; E F, counter-shafts; G, a hand-lever pivoted to the frame-work and supporting a tightener-pulley; and the numerals 1 to 12, inclusive, the various pulleys, belts, and gears for driving and operating the machine.

The frame A is adapted to support the table, having ways for slides thereon, and the mechanism of the planer being provided with It also has a shaft, A, for adjusting the bed B. r

The bed 13 is mounted in the frame A and is vertically adjustable therein. This bed has downWardly-projecting slides 13, which terminate in lugs 11, which are tapped to receive the screw-rods a. Said screw-rods, are connected by means of initergears witl1 the shaft A, and thus, by turning this shaft the verti- It is desirable that hoops should be beveled, and the table is grooved, as shown most plainly in Fig. 2, in order that this may be effected without making one corner of the planer-knives longer than the other. A stop, I), is mounted on the table alongside of each of these grooves to determine the position of the hoop-blank as it is passed into and through the machine. These stops are secured by a bolt passing through a groove in the table, as shown, and are thus rendered adjustable. Springs b are placed 011 the other side of the grooves to hold the blanks against said stops. This arrangement insures the utmost accuracy in the position of the hoops during the process of planing. Upon the front side of and close to the cutterhead are guides I), through which the blanks pass, and the stem of which extends down through the table and through a rubber spring,

b. Heretofore the end of the blank or hoop, as

soon as relieved from the pressure of the feedroll D, was apt to raise somewhat from the bed and thus be planed too thin and spoiled. By the use of these guides the hooks are held down closely upon the bed until completely planed, and several inches in thelength of each'hoop is thus saved-that is, the blanks can be cut several inches shorter than heretofore to produce the samelength of perfect hoop. The springs 7) permit the guides to rise slightly in case of inequalities in the blanks, or in case a splinter or shaving should get upon or under the hoops in passing through the planer. A roll, D is placed as close to the cutter-head as possible on the rear side to hold the hoop down firmly against the table at that point, thus overcoming all tendency that the hoop might have to spring up, and thus be planed thinner than is desired.

The cutter-head G is mounted on its shaft C, which rests in ordinary hearings in the frame-work. The knives c thereon have their cutting-edges formed to shape desired. Said cutter-head is driven by a belt, 9, running to the pulley 1 upon its shaft 0. Upon the other end of its shaft is a pulley, 2, from which the various feedrolls are driven by means of the system of gearing which will be presently described.

The feed-rolls D D should be corrugated, and the feed-rolls D" D and the pressureroll plane hoops in the D shouldbe smooth. These rolls are mounted in journal-bearings d on the frame-work, as shown. There is used in connection with each of these bearings a rubber or other spring, (Z which permits the rolls .to yield sufficiently to accommodate the inequalities, if any, in. the hoop-blanks, and' at the same time hold said hoop-blanks tightly against the table. Upon the shaft of each feed-roll is a spur-gear wheel, as shown, by which said roll is driven. The rolls 1) D are grooved circumferentially to correspond with the grooves in the table 13.

The counter-shafts E F may be any ordinary counter-shafts desired. They are shown as fixed shafts,with the wheels and pulleys revolving thereon.

The hand-lever G is a convenient combined support for the ti ghtenenpulley 12, and means for throwing said pulley into or out of contact with the belt 10. By its use the operator is enabled to conveniently control the passage of the hoop -blanl through the machine.

The several pulleys,belts,and' gears operate as follows: The main belt 9 drives the pulley 1,and thus the cutter-head shaft, cutter-head, and pulley 2. The pulley 2,through the belt 10,drivcs the pulley 8 011 the counter-shaft E, and also the pulley 4 on the same shaft therewith. Said pulley 4, through the belt 11, drives the pulley 5 and the spur-gear wheel 6 on the same shaft therewith. Said wheel 6 to remain at rest, at pleasure.

meshes into and drives the spur-gear wheels 7 and S, andthus drives the 'l'eed-rolls D and I). I

A tightener-pulley, 12, suitably mounted on the framework, is adapted to be thrown into or out of contact with the belt 10, and thus cause the feed-rolls to revolve or permit them A hand-lever, G, provided with a stud-shaft, g, is shown as the mounting for. this pulley, and a ratchet, a, 011 the frame A, is shown as the means of securing it in the desiredposition.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hoop-planer, the supporting-frame,

the cutter-head, and feedrolls, shafts, gearing,

and operative mechanism whereby motion is given to the cutter-head and feed-rolls, in combination with the clampguides b yhaving bolts and rubber springs, and means for securing the same in position, substantially as and for the purpose set forth.

2. The combinat'on, with the bed and cutter-heads of a hoop-planer, of a series ofclamplike guides, b, adjustably held against said bed by means of bolts and rubber springs, substantially as shown and specified.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 13th day of January, A. D. 1883.
